As more and more quality of life becomes a goal of personnel and sustainable development, long-distance travel is becoming more widespread. Sailing around the world is an example of this evolution. The keys to a successful journey are rigorous preparation and adherence to some prevention rules. Medical or surgical emergencies are rare, and can often be dealt with by remote medical contact. New communication technologies such as satellite phones make it possible to seek medical advice from professionals, or even for sailers to treat themselves with very short prior training, provided that the required equipment and medicines have been embarked before leaving. Sophisticated rescue can also be organized. These technological innovations have changed the security and lives of sailors and explorers in remote areas of the world.
